SAFE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 331,480, dated December1., 1885.

Application filed April 14, 1885. Serial No. 162,198. (Modeh) To allwhom it may concern.-

Be it known that I, CARL DIEBOLD, of Canton, in the county of Stark andState of Ohio, have invented certain new and usefullmprovements in SafeAttachments; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use the same.

My invention relates to improvements in safe attachments, the objectbeing to provide a presser-bar and double door-hinges, with the rearhinges rigidly connected by an axial rod, a stop arranged to limit-theoutward movement' of the rear portion of the hinges, to the end that inclosing the safedoor the wrists of the presser-bar will enter therespective grooves in the cam-blocks automatically, and the door bymeans of the presser-bar on its near approach to its seat will be keptparallel with the seat.

A further object is to provide acombination of mechanism whereby thedial of the combination lock and the bolt-shifting lever or handle maybe arranged on opposite sides of the presser-bar, although the lock andthe internal connections with the bolt-shifting mechanism may bedirectly behind the presser-bar.

With these objects in view my invention consists in certain features ofconstruction and in combination of parts hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a safewith my improvements thereon. Figs. 2 and 3 are elevations in transversesection of the door and casings, the former showing the position of thedoor when the presser-bar is in position to be operative, and the lattershowing the door closed. Fig. 4 is a View in perspective of a portion ofthe safe, showing the rear portion of the hinges at the limit of theiroutward movement, and showing the rear cam-block and the groovestherein. Figs. 5, 6, and 7 are views in perspective respectively of thecam-blocks, presser-bar, and attachments. Fig. 8 is a view inperspective and partly in section of the mechanism respectively forconnecting the dial and hand-lever with the lock and bolt-shiftingdevice.

A represents the safe, and B the safe-door,

groove 9.

with the dial 5, for operating the combinationlock, and the lever orhandle I), for shifting the door-bolts. The door and casing are tonguedand grooved, as shown, with packing, a, in the groove of the latter,arranged in the usual manner, and this construction necessitates theemployment of some means for keeping the door parallel with its seat asitapproaches and engages the latter. For this purpose I employ doublehinges and a presser-bar arranged as follows: The parts 0 of the hingesare attached to the door and jointed to the parts 0 in the usual manner.The latter is rigidly attached to the axial rod 0, that is journaled inthe parts 0, and the latter is secured to the safe, as shown. With thisarrangement of parts the two sets of hinges of course move in unison. Alug, 0 attached to the rod 0, or to one of the parts 0, as may bepreferred, by its engagement with the safe limits the outward movementof the rear portion of the hinges, while the forward joint of the hingesis left free.

D is the presser-bar, arranged in the form of a rock-shaft, andjournaled in the blocks (1, that are attached to the door and providedwith the hand-lever D. The enlarged ends of the bar, have wrists d and(i that are in line with each other, but are eccentric with the axis ofthe presser-bar. These wrists engage grooves respectivelyin thecam-blocks E and F, that are attached to the safe on the opposite sidesof the door, as shown. These blocks have each a vertical groove,respectively, e and f, and lateral grooves. e and f, the former, 6,leading from the upper portion of the groove-e forward to the face ofthe block E, and the groove f leading from the groove f rearward. Therelation of parts is such that with the lever D turned down, as shown insolid lines in Fig. 6, the wrists d and d are above the axis of thepresser-bar, and the wrist d is in position to enter the With thisposition of parts when the door is closed by hand the wrists d and dwill be respectively in the upper part of the vertical grooves eand f,after which, if the lever D is turned up to or toward the position shownin Fig. 1, and in dotted lines in Fig. 6, the wrists will descend in therespective grooves e and f, and by reason of their eccentricity with thepresser-bar will force a limited distance, the rear portion, 0, of thedouble hinge need not move but a short distance, and is thereforelimited, as aforesaid, by the lug 0,- but in so doing an important endis attainedto wit, the axial line of the forward part of the hinge iskept so near the safe that the wrist (1 will always enter the grooves inthe block F, and this, too, without 'any guiding of the door by theoperator or otherwise.

Double hinges have heretofore been used on safe-doors, some of whichwould admit of the door engaging the safe edgewise if it were not guidedby the operator. With the construction shown the door, when swung to,however carelessly, will automatically assume its proper position toengage the seat, and the wrists of the presser-bar will find their wayto their respective places in the cam-blocks.

Where this mechanism is attached to large doors for the outside of safesor vaults, it may be advisable to use two presser-bars, arranged the oneabove the other on the door, and in such case the levers D might beconnected by a bar or link, so'that by moving one lever, D, bothresser-bars would be simultaneously operated. This mechanism is alsoused on small doors inside the safe or vault when it is necessary toeconomize the space on the face of the door, so that after attaching thehinges there will be room for locating the dial, lever b, and thepresser-bar, and have them all accessible and convenient. Thepresser-bar should be located across the center of the door, to equalizethe pressure on the seat. WVith small doors the combination-lock islikely to cover the greater part of the inside of the door, and musttherefore be located about centrally, at least in a vertical direction,and the only available space on the outside of the door for the dial andbolt shifting lever are respectively above and below the presserbar.

To connect the dial and lever with the internal mechanism, I have hadrecourse to a modification of devices for which Letters Patent of theUnited States were granted to A. G. Burton, dated February 1, 1870, No.99,400, the essential features of which are shown in Fig. 8.

The spindle H of the dial has a gear, H, and the lock-spindle I has agear, I, with one or more intermediate gears, h. The spindle 'J of thelever D has a gear, J, and the spindle K of the bolt-shifting mechanismhas a gear, K. By arranging the gears H and one or more intermediategears, h, above the gear I the dial is brought above the presser-barapproximately, as shown in dotted lines, Fig. 1. By arranging the gear Jbelow the gear K, and if necessary using one or more intermediate gears,the lever D may be located below the presser-barfor instance, as shownin Fig. 1. WVith this construction of parts the dial, bolt-shiftinglever, and presser-bar may be conveniently located 011 a door so smallthat the available space on the door is about all taken up with theseparts and the necessary room for operating them.

WVhat I claim is 1. In safe attachments, double door-hinges, a stop tolimit the outward movement of the intermediate part of the hinges, apresser-bar arranged on the door, and suitable engaging cam-blocksarranged on either side of the door and so arranged that in operatingthe door the latter will automatically swing to its place in the casingand the wrists or ends of the presser-bar will automatically enter therespective places in the cam-blocks, substantially as set forth.

2. The combination, with a door and a .presser-bar secured thereto, ofthe spindles H, I, J, and K and the gearing the above parts beingcombined. and arranged substantially as described.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 4th day of April, 1885.
